| 24 NAME | |
| 25 hpplay | |
| 26 PURPOSE | |
| 27 Play .au sound files on hp9000s700 | |
| 28 BUGS | |
| 29 I have been unable to figure out how to use the volume feature, so no | |
| 444 | 30 attempt has been made to honor the volume arg of play_sound_* |
| 428 | 31 This means that all sounds are played at 100%. |
| 32 The gain parameter can be set by using the hp-play-gain variable. | |
| 33 | |
| 34 NOTES | |
| 35 This file is mostly based on the player program found in the examples | |
| 36 directory of the audio software delivered on our machines. The path I | |
| 37 found it under was /usr/audio/examples/player.c | |
| 38 This file contained no credits and no copyrights. The original fileheader | |
| 39 is given below. | |
